I'm not suggesting that anyone try to correct an electrician's terminology, just that they use the correct one themselves, at least at first.

The NEC requires EVSE's to be a continuous load and they limit the current to 80%. Thus a 40A circuit is good for a max of 32A and a 20A circuit is good for 16A.

I really doubt the 20A circuit is wired with #10 gauge wires since #12 is good for 20A.

I sent off our Nissan EVSE to evseupgrades.com, for the 240V mod.
I had found a 10-30 dryer outlet in the garage in our rented house.
I have since replaced it with a Leviton L6-30R.

You think about "well I MIGHT drive all morning, then come
back and need to charge at lunch and then drive a bunch
more in the evening." If the Leaf is your only car and you
are running kids around all day or something then OK
it makes sense then.

For most people the effort+money to install a 50A circuit
and a 6+ KWh charger, is a desire more than actual need.

We charge overnight. The 3.x KWh rate is sufficient for everyday needs.
